tegra132: prepare cpu startup in psci
In order to start CPUs while in secmon/psci one needs to
set up the proper SoC state. Therefore, refactor the current
CPU startup API to allow for this by adding cpu_prepare_startup()
and start_cpu_silent().
BUG=chrome-os-partner:32136
BRANCH=None
TEST=Built and booted kernel.
